2016-08-26ARM: OMAP2+: use IS_ENABLED() instead of checking for built-in or moduleJavier Martinez Canillas1-2/+1
The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Using the macro makes the code more readable by helping abstract away some of the Kconfig built-in and module enable details.

2012-11-21ARM - OMAP: ads7846: fix pendown debounce settingIgor Grinberg1-14/+20
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the pendown GPIO debounce time setting by the below sequence: gpio_request_one() gpio_set_debounce() gpio_free() It also revealed a bug in the OMAP GPIO handling code which prevented the GPIO debounce clock to be disabled and CORE transition to low power states. Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on free/reset) fixes the OMAP GPIO handling code by making sure that the GPIO debounce clock gets disabled if no GPIO is requested from current bank. While fixing the OMAP GPIO handling code (in the right way), the above commit makes the gpio_request->set_debounce->free sequence invalid as after freeing the GPIO, the debounce settings are lost. Fix the debounce settings by moving the debounce initialization to the actual GPIO requesting code - the ads7846 driver.

2012-10-15ARM: OMAP2+: nand: unify init functionsAfzal Mohammed1-45/+0
Helper function for updating nand platform data has been added the capability to take timing structure arguement. Usage of omap_nand_flash_init() has been replaced by modifed one, omap_nand_flash_init was doing things similar to board_nand_init except that NAND CS# were being acquired based on bootloader setting. As CS# is hardwired for a given board, acquiring gpmc CS# has been removed, and updated with the value on board. NAND CS# used in beagle board & omap3evm was found to be CS0. Thomas Weber <thomas.weber.linux@googlemail.com> reported that value of devkit8000 to be CS0. Overo board was found to be using CS0 based on u-boot, while google grep says omap3touchbook too has CS0.

2012-09-12ARM: OMAP2+: Prepare for irqs.h removalTony Lindgren1-0/+1
As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures. Note that for drivers/staging/tidspbridge we just define things locally. Cc: Paul Walmsley <paul@pwsan.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2012-08-06Revert "ARM: OMAP3530evm: set pendown_state and debounce time for ads7846"Igor Grinberg1-11/+0
1) The above commit introduced a common ->get_pendown_state() function into the generic code, but that function was board-specific for the OMAP3EVM and thus broke most other boards using this code. 2) The above commit was mis-merged introducing another bug which prevents the ads7846 driver probe function to succeed. The omap_ads7846_init() function frees the pendown GPIO in case there is no ->get_pendown_state() function set by the caller (board specific code), so it can be requested later by the ads7846 driver. The above commit add a common ->get_pendown_state() function without removing the gpio_free() call and thus once the ads7846 driver tries to use the pendown GPIO, it crashes as the pendown GPIO has not been requested. 3) The above commit introduces NO new functionality as get_pendown_state() function is already implemented in a suitable way by the ads7846 driver and the debounce time handling has already been fixed by commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code).

2012-07-06ARM: OMAP3530evm: set pendown_state and debounce time for ads7846Zumeng Chen1-2/+16
Currently most ads7846 config definitions for OMAP3 series boards have been moved to common-board-devices.c, and it is transparent for init. And it's no very proper to do gpio_request based on get_pendown_state since omap_ads7846_init knows everything about ads7846_config. So it's more fit to request gpio according to the right gpio_pendown and set debounce time conditionally. If we don't set proper debouce time, there are flooded interrupt counters of ads7846 responding to one time touch on screen, then the driver couldn't work very well.

2011-06-29omap: cleanup NAND platform dataGrazvydas Ignotas1-4/+2
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and 'dma_channel' are never referenced by the NAND driver, yet various board files are initializing those fields. This is both incorrect and confusing, so remove them. This allows to get rid of a global variable in gpmc-nand.c. This also corrects an issue where some boards are trying to pass NAND 16bit flag through .options, but the driver is using .devsize instead and ignoring .options. Finally, .dev_ready is treated as a flag by the driver, so make it bool instead of a function pointer.
