ARM: OMAP2+: Remove legacy serial.c

2016-11-10T15:53:18+00:00

We can now initialize the UARTs using device tree. Signed-off-by: Tony Lindgren

ARM: OMAP: serial: Rename DRIVER_NAME

2016-02-07T07:13:30+00:00

DRIVER_NAME is too generic to be used in a driver-specific platform data file. Use a name specific to the driver instead, to avoid collisions. Signed-off-by: Jean Delvare Acked-by: Tony Lindgren Cc: Jiri Slaby Signed-off-by: Greg Kroah-Hartman

ARM: OMAP2+: Change core_initcall levels to postcore_initcall

2015-12-03T19:38:09+00:00

We want to be able to probe a few selected device drivers before hwmod code populates the clocks in omap_hwmod_setup_all(). This allows us to convert most of the clock drivers into regular device drivers. We only need a few minimal clock drivers early for the system timers to select between the 32KiHz clock and the high frequency oscillator. With these changes, initializing the clock drivers can be just done at core_initcall time with something like: np = of_find_node_by_name(NULL, "plls"); if (np) of_platform_populate(np, NULL, NULL, NULL); And then these clocks will be available for the interconnect code to use. Having most of the clock drivers being regular device drivers allows us to use the nice things like devm_* functions and dev_err and dev_dbg. As an extra bonus, this also allows us to develop the clock drivers for new SoCs as loadable modules initially for cases where we can boot up the system based on the bootloader configured clocks. To do this, let's change the core_initcalls to postcore_initcall under mach-omap2. Cc: Felipe Balbi Cc: Grygorii Strashko Cc: Paul Walmsley Cc: Tero Kristo Signed-off-by: Tony Lindgren

ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL

2013-07-30T11:13:35+00:00

With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+: Fix serial init for device tree based booting" stubbing out omap_serial_early_init() for Device tree based booting, there was a crash observed on AM335x based devices when hwmod does a _setup_reset() early at boot. This was rootcaused to hwmod trying to reset console uart while earlycon was using it. The way to tell hwmod not to do this is to specify the HWMOD_INIT_NO_RESET flag, which were infact set by the omap_serial_early_init() function by parsing the cmdline to identify the console device. Parsing the cmdline to identify the uart used by earlycon itself seems broken as there is nothing preventing earlycon to use a different one. This patch, instead, attempts to populate the requiste flags for hwmod based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need for cmdline parsing in the DT as well as non-DT cases to identify the uart used by earlycon.

Pull ARM SoC cleanups from Arnd Bergmann: "This contains cleanups as preparation for other branches adding new features, we pulled 16 branches for 9 platforms into this one. Most notable here is the removal of support for ATAGS based OMAP4 systems. Since all OMAP4 machines are fully functional with DT based booting in 3.10, we can remove a lot of code here. Also noteworthy is Maxime Ripard's cleanup of the machine descriptors, which means we need no machine descriptors in a lot more cases and can boot additional machines by just having the respective device drivers enabled." * tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (76 commits) ARM: picoxcell: remove .nr_irqs reference ARM: s5p64x0: avoid build warning for uncompress.h ARM: SAMSUNG: Remove unused plat/regs-watchdog.h header ARM: SAMSUNG: Remove legacy watchdog reset code ARM: SAMSUNG: Let platforms use the new watchdog reset driver ARM: SAMSUNG: Add watchdog reset driver ARM: SAMSUNG: Use local definitions of watchdog registers watchdog: s3c2410_wdt: Use local register definitions ARM: S5P64X0: Use common uncompress.h part for plat-samsung ARM: SAMSUNG: Consolidate uncompress subroutine ARM: at91: drop rm9200dk board support ARM: dts: msm: Fix merge resolution ARM: OMAP1: Remove dma.h ARM: OMAP1: Remove legacy irda.h and irda setup from board files ARM: OMAP1: Remove duplicated DMA channel definitions ARM: OMAP1: Remove McBSP DMA channel definitions ARM: OMAP2+: Remove dma.h ARM: OMAP2+: hwmod: Remove remaining DMA channel definitions ARM: OMAP2+: Remove duplicated DMA channel definitions ARM: OMAP2+: Remove AES crypto device DMA channel definitions ...
