2019-02-19ARM: davinci: cp-intc: add a wrapper around cp_intc_init()Bartosz Golaszewski1-1/+1
We're going to extend the cp_intc_init() function with a config structure so we can drop the intc-related fields from davinci_soc_info. Once we do it, we won't be able to use this routine directly as the init_irq callback. Wrap the calls in additional helpers that don't take parameters and can be assigned to init_irq.

2019-02-19ARM: davinci: make irqs.h a local headerBartosz Golaszewski1-2/+3
The existence of irqs.h in mach-davinci/include/mach only makes sense without SPARSE_IRQ as it's then expected to define NR_IRQS and is included from asm/irq.h. As we now support SPARSE_IRQ, this header can be moved to mach-davinci and used as the source of HW interrupt numbers. While updating the includes in various files - also rearrange the headers by directory (linux/asm/mach).

Using device properties only will allow us to significantly simplify the at24 configuration code. Remove the at24_platform_data structure and replace it with an array of property entries.

This moves the call of davinci_clk_init() from map_io to init_time for all boards. This is the proper place to init clocks. This is also done in preparation for moving to the common clock framework. dm646x is a special case because we need to handle different ref_clk rates depending on which board is being used. The clock init in this case is modified to set the rate before registering the clocks instead of using davinci_set_refclk_rate() to recalculate the entire clock tree after all of the clocks are registered. Also, the cpu_clks field is removed from struct davinci_soc_info since it is no longer needed. Signed-off-by: David Lechner <david@lechnology.com> Signed-off-by: Sekhar Nori <nsekhar@ti.com>

2018-02-19ARM: da8xx: use platform data for CFGCHIP syscon regmapDavid Lechner1-4/+0
This converts from using a platform device for the CFGCHIP syscon regmap to using platform data to pass the regmap to consumers. A lazy getter function is used so that the regmap will only be created if it is actually used. This function will also be used in the clock init when we convert to the common clock framework. The USB PHY driver is currently the only consumer. This driver is updated to use platform data to get the CFGCHIP regmap instead of syscon_regmap_lookup_by_pdevname().

2016-11-28ARM: davinci: da830-evm: use gpio descriptor for mmc pinsAxel Haslam1-30/+11
Currently the mmc driver is polling the gpio to know if the card was removed. By using a gpio descriptor instead of the platform callbacks, the driver will be able to register the gpio using the mmc core APIs designed for this purpose. This has the advantage that an irq will be registered, and polling is no longer needed. Also, a dependency on platform callbacks is removed for this board.

Up to this point, the USB phy clock configuration was handled manually in the board files and in the usb drivers. This adds proper clocks so that the usb drivers can use clk_get and clk_enable and not have to worry about the details. Also, the related code is removed from the board files and replaced with the new clock registration functions. This also removes the #if IS_ENABLED(CONFIG_USB_MUSB_HDRC) around the musb declaration and renames the musb platform device so that we can reference it from the usb20 clock even if the musb device is not used.

2016-10-31ARM: davinci: da8xx: Add full regulator constraints for non-DT bootAxel Haslam1-0/+3
The phy framework requests an optional "phy" regulator. If it does not find one, it returns -EPROBE_DEFER. In the case of non-DT boot for the omap138-lcdk board, this would prevent the usb11 phy to probe correctly and ohci would not enumerate. By calling regulator_has_full_constraints(), An error would be returned instead of -EPROBE_DEFER for the regulator, and the probe of the phy driver can continue normally without a regulator.

The problem that the set timings code contains the call of Davinci platform function davinci_aemif_setup_timing() which is not accessible if kernel is built for another platform like Keystone. The Keysone platform is going to use TI AEMIF driver. If TI AEMIF is used we don't need to set timings and bus width. It is done by AEMIF driver. To get rid of davinci-nand driver dependency on aemif platform code we moved aemif code to davinci platform.

2013-01-03ARM: davinci: da8xx_register_spi() should not register SPI board infoVivien Didelot1-2/+7
Without this patch, da8xx_register_spi() registers the SPI board info, the SPI controller, and sets its number of chipselect to the size of the static spi_board_info array. This is bad because a SPI board info may declare devices for different SPI buses, and because other code can also call spi_register_board_info() (e.g. a daughter board might provide additional SPI devices). This patch removes the spi_register_board_info() call from da8xx_register_spi(), renames this last one to da8xx_register_spi_bus() to be more explicit, takes the number of chipselect as a function parameter, and updates the impacted board-da8{3,5}0-evm.c, and board-mityomapl138.c files accordingly. It also sets the SPI platform data static, as it doesn't need to be exported.

2012-12-24ARM: delete struct sys_timerStephen Warren1-1/+1
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2011-09-11mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris1-1/+1
Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

2011-09-11mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris1-1/+1
This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.
