2022-09-21iio: adc: ad7923: support extended rangeNuno Sá1-1/+6
By default the driver was always setting the RANGE bit which means that the analog input goes from 0 to VREF. However, we might want to have 0 to 2xVREF. This change adds a new Firmware property to allow for the extended range while keeping the default behavior if nothing is provided.

2022-09-21iio: adc: ad7923: fix channel readings for some variantsNuno Sá1-1/+3
Some of the supported devices have 4 or 2 LSB trailing bits that should not be taken into account. Hence we need to shift these bits out which fits perfectly on the scan type shift property. This change fixes both raw and buffered reads.

2022-09-21drivers: iio: adc: ltc2497: Rename the LTC2499 iio deviceCiprian Regus4-1/+13
Set the iio device's name based on the chip used for the LTC2499 only. The most common way for IIO clients to interact with a device is to address it based on it's name. By using the dev_name() function, the name will be set based on a i2c_client's kobj name, which has the format i2c_instance-i2c_address (1-0076 for example). This is not ideal, since it makes a requirement for userspace to have knowledge about the hardware connections of the device. The name field is set to NULL for the LTC2497 and LTC2496, so that the old name can kept as it is, since changing it will result in an ABI breakage.

2022-09-21iio: ltc2497: Fix reading conversion resultsUwe Kleine-König1-0/+13
After the result of the previous conversion is read the chip automatically starts a new conversion and doesn't accept new i2c transfers until this conversion is completed which makes the function return failure. So add an early return iff the programming of the new address isn't needed. Note this will not fix the problem in general, but all cases that are currently used. Once this changes we get the failure back, but this can be addressed when the need arises.

Today remove callbacks of platform devices return an int. This is unfortunate because the device core ignores the return value and so the platform code only emits a warning (and still removes the device). The longterm quest is to make these remove callbacks return void instead. This series is a preparation for that, with the goal to make the remove callbacks obviously always return 0. This way when the prototype of these functions is changed to return void, the change is straight forward and easy to review.

2022-09-20habanalabs/gaudi: use 8KB aligned address for TPC kernelsTomer Tayar1-3/+4
I$ prefetch is enabled when sending a TPC kernel to initialize the TPC memory, and it has a restriction that the base address will be aligned to 8KB. Currently the base address is 128 bytes from the start address of the device SRAM, so prefetching will start 128 bytes before the actual kernel memory. Modify the kernel address to be 8KB aligned.

2022-09-20habanalabs: remove some f/w descriptor validationsfarah kassabri1-29/+14
To be forward-backward compatible with the firmware in the initial communication during preboot, we need to remove the validation of the header size. This will allow us to add more fields to the lkd_fw_comms_desc structure. Instead of the validation of the header size, we just print warning when some mismatch in descriptor has been revealed, and we calculate the CRC base on descriptor size reported by the firmware instead of calculating it ourselves.

2022-09-19habanalabs/gaudi2: increase hard-reset sleep time to 2 secTomer Tayar1-1/+1
The access to the device registers is blocked during hard reset, until preboot runs and allows the access to specific registers, including the PSOC BTM_FSM register which is used to know when the reset is done. Between the reset request and until this register is polled there is a small delay of 500 msec which is not enough for F/W to process the reset and for preboot to run, so the register might be accessed while it is blocked. To avoid it, increase the delay to 2 sec. Signed-off-by: Tomer Tayar <ttayar@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>

The code used the mmu mutex to protect access to the context's page tables and invalidation of the MMU cache. Because pgt are per context, the mmu mutex was a member of the context object. The problem is that the device has a single MMU invalidation h/w (per MMU). Therefore, the mmu mutex should not be a property of the context but a property of the device.

cb_map_mem() uses gen_pool_alloc() to get virtual address for mapping a CB. The mapping is done in chunks of page size, so if the CB size is larger, it is possible that the allocated virtual addresses won't be consecutive. User retrieves this device VA which returns the virtual address in the first va_block. If there is a "hole" in the virtual addresses, user can configure a HW block with a bad device VA.
