2012-04-12wlcore/wl12xx: set HT capabilities per chip-familyArik Nemtsov1-0/+3
Set HT capabilities in the low-level HW driver. These are then used by wlcore when registering with mac80211. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw op to get rate-mask for AP-link in STA modeArik Nemtsov1-0/+2
In some chip-families, there are operating modes where we must mask-out certain Tx rates, and/or tweak the rate-mask with special HW-specific bits. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: move runtime configuration struct to the lower driverLuciano Coelho1-1/+1
The configuration parameters vary with different chip families. Some of the parameters used only by some chip families, others should have different value depending on the family. Thus move the configuration values from wlcore to wl12xx. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: expand functionality of cmd_trigger HW opArik Nemtsov1-1/+2
Change the cmd_trigger op to include the write of the command buffer. Also, instead of letting the lower driver access the cmd_box_addr element directly, we now pass the address in the trigger_cmd operation, so it doesn't have to be exported.

2012-04-12wlcore/wl12xx: add hw op for vif initArik Nemtsov1-0/+1
Add an op for family-specific vif initialization. Currently unused, but will be needed when wl18xx support is implemented. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw_init operationLuciano Coelho1-0/+1
Move all the wl12xx-specific hw initialization procedures into a new hw_init op. Move some commands and ACX functions to wl12xx. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: turn no-Tx-align quirk into Tx-alignArik Nemtsov1-1/+1
Inverting the quirk flag to indicate Tx-alignment. This aligns it with the similar Rx-side quirk. The call to wl1271_set_block_size() decides whether SDIO block size alignment can be used or not. In case we're using SPI, we can't use the block size alignment, so the function returns false. So we set the quirk when wl1271_set_block_size() returns true and let the wl12xx lower driver unset the bit for wl127x (since it doesn't support this quirk).

2012-04-12wlcore/wl12xx: split Tx completion to immediate/delayedArik Nemtsov1-0/+2
One chip family employs immediate Tx completion, where knowledge of completed packets is given as part of the FW status. Another is only notified of Tx completion via the FW status, and has to read the completion status of the packets from a different location. Implement the wl12xx tx completion as a delayed Tx completion. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw op for getting rx packet data lengthArik Nemtsov1-0/+3
There is a difference in the way chip families report the length of data in a single Rx packet. Abstract this into a HW op. Refactor the Rx data handling function to allocate the correct size for the data, and avoid trimming the skb. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add prepare_read hw op for Rx dataLuciano Coelho1-0/+1
The only difference in the read_data operations is that some chips need to prepare the data to be read before reading. So instead of having a mandatory read_data operation, we now have an option prepare_data operation that only needs to be implemented for chips that require it. In the wl12xx lower driver, we only set the prepare_data operation for wl127x chips.

2012-04-12wlcore/wl12xx: add hw op for getting rx buffer data alignmentArik Nemtsov1-2/+5
An aligned data buffer is such where the Ethernet portion of the packet starts on a 4-byte boundary. Some chip families support padding the Rx data buffer to achieve such alignment, others rely on the host to perform it. Implement the HW op for getting alignment state in wl12xx. Add support for HW-padded alignment in the Rx flow. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore: introduce Rx block-size alignment HW quirkArik Nemtsov1-0/+3
For chip-families that support aligned buffers in the Rx side. The Rx flow changes slightly for these chips. Currently these modifications rely on a hard-coded block-size of 256. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add global elements to convert hw-rates to standard ratesArik Nemtsov1-0/+9
Rates reported by HW can be different between chip families. Make the rate-to-idx translation tables private per family and use them in a common translation function. Add a global element to help determine which rates are HW HT-rates. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw op for setting frame length in tx_hw_descArik Nemtsov1-0/+3
Each chip family indicates the length of a frame to the HW differently. This includes different padding, alignment and other fields in the HW Tx descriptor. Put all wl12xx specific code in a hw op. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw op for setting blocks in hw_tx_descArik Nemtsov1-0/+5
Each chip family has a slightly different Tx descriptor. Set the descriptor values according to family. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add hw op for calculating hw block count per packetArik Nemtsov1-0/+1
Each chip family has a different block size and calculates the total number of HW blocks differently, with respect to alignment. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: change GEM Tx-spare blocks per-vifArik Nemtsov1-3/+4
The number of spare Tx blocks must be changed when the GEM cipher is engaged. Track set_key() operations to see if this is the case and change the Tx HW spare block count accordingly. Set the number of spare blocks for each operating mode from the low level driver. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: set the number of Tx descriptors per chip familyArik Nemtsov1-2/+8
Each chip family can have a different amount of Tx descriptors. These are set on init. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: create per-chip-family private storageArik Nemtsov1-1/+4
This storage is allocated in wlcore_alloc_hw and freed in free_hw. The size of the storage is determined by the low-level driver. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore: add quirk to disable ELPLuciano Coelho1-0/+3
ELP is a very complicated process in the firmware. Due to its complexity, in some early firmware revisions, the ELP feature is disabled. To support this cases, this patch adds a quirk that disables ELP mode. When ELP is not supported, do not attempt to enter ELP when requested by the driver.

2012-04-12wlcore: remove some unnecessary event mailbox address readsLuciano Coelho1-1/+0
We were reading the even mailbox address three times, which was completely unnecessary and complicated things regarding partition selection. Remove the unnecessry reads and set the address for mailbox 1 and 2 after the first read. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add quirk for legacy NVS supportLuciano Coelho1-0/+3
Instead of checking the chip ID directly in the wlcore code to decide whether to use the new or the old NVS format, we now use a quirk that should be set by the low level driver to say that it needs to use the old format. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add command trigger and event ack operationsLuciano Coelho1-16/+2
Different chips may use different bits in the interrupt trigger register. Add operations to handle these differences. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: move MAC address reading operation to lower driverLuciano Coelho1-0/+1
Different chip families have the factory MAC address written in different places. Add a new hardware operation to read the MAC address, if available. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: move top initialization to wl12xxLuciano Coelho1-0/+1
The top registers initialization is very specific to the actual hardware used, even the way in which we read from and write to the top registers varies from chip to chip. This patch moves all top registers initialization to wl12xx. Also add a boot op for the wlcore module to call at the right time and a few callbacks with the common called to be called from the lower drivers boot operations. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: move get_pg_ver to the lower driverLuciano Coelho1-0/+1
The PG version depends on the actual hardware. This commit moves the code used to read the PG version to the lower driver, by adding the get_pg_ver hardware operation. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: add chip-specific identify chip operationLuciano Coelho1-0/+18
Move the code that identifies the chip ID and selects the appropriate firmware to an operation implemented by the lower driver. Also move the quirks definitions into wlcore.h and rename to WLCORE_QUIRK_*. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: implement chip-specific register tablesLuciano Coelho1-0/+107
Add register tables support in wlcore, add some new IO functions to read and write to chip-specific register and data addresses. Move some common register values from wl12xx to wlcore and add the registers table to wl12xx. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wlcore/wl12xx: implement chip-specific partition tablesLuciano Coelho1-1/+26
Add partition tables to wlcore, move and reorganize partition setting functions. Move wl12xx partition table to use the wlcore partition table instead. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wl12xx/wlcore: move wl1271 struct to wlcore and add opsLuciano Coelho1-0/+219
In order to add chip-specific operations and prepare for future elements that need to be set by the lower driver, move the wl1271 structure to the wlcore.h file and add an empty placeholder for the operations structure. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wl12xx/wlcore: initial split of probeLuciano Coelho1-1/+6
We need to set some parameters (eg. partition and register tables) during probe of the lower driver, so split the probe function, leaving most of it in wlcore, but moving the hw struct allocation to the lower driver. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-04-12wl12xx/wlcore: spin out the wl12xx probe from wlcore to a new wl12xxLuciano Coelho1-0/+28
Create a new small wl12xx module that only contains the probe functions and depends entirely on wlcore otherwise. Signed-off-by: Luciano Coelho <coelho@ti.com>
