OMAP2/3 board-*.c files: read bootloader configuration earlier Most board-*.c files read configuration data from the bootloader in their .init_machine() function. This needs to happen earlier, at some point before omap2_init_common_hw() is called. This is because a future patch will use the bootloader serial console port information to enable the UART clocks earlier, immediately after omap2_clk_init(). This is in turn necessary since otherwise clock tree usecounts on clocks like dpll4_m2x2_ck will be bogus, which can cause the currently-active console UART clock to be disabled during boot.

ARM: OMAP2+: DT 'compatible' tweak for displays As there is no common panel framework in the kernel, we have OMAP specific panel drivers. However, the DT data should be generic. This brings the issue that some other platform could use the same panels, and would need to create a driver with the same 'compatible' string as the OMAP driver. In the long run, we have to get a common panel framework. For the time being, this patch solves the issue: At early boot time, we go through the DT nodes looking for the panels the kernel supports for OMAP. For each found node, the 'compatible' string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes "omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss," at the beginning of their compatible field. This allows us to have generic DT data, but OMAP specific display drivers.

This allows the generic late initializations such as cpufreq hooks to be active. Based on out-of-tree patches that need to be introduced in mainline, this introduction allows us to provide the foundation for further SoC specific features as they are developed.

ARM: OMAP2+: Simplify system timers definitions There is a lot of redundancy in the definitions for the various system timers for OMAP2+ devices. For example, the omap3_am33xx_gptimer_timer_init() function is the same as the omap3_gp_gptimer_timer_init() function and the function omap4_sync32k_timer_init() can be re-used for OMAP5 devices.

AM43x is similar to AM335x w.r.t L4 PER/WKUP memory map. AM43x has a sync timer, here that is being used as clocksource, while 1ms dmtimer as clockevent.

ARM: OMAP2+: AM43x: Use gptimer as clocksource The SyncTimer in AM43x is clocked using the following two sources: 1) An inaccuarte 32k clock (CLK_32KHZ) derived from PER DPLL, causing system time to go slowly (~10% deviation). 2) external 32KHz RTC clock, which may not always be available on board like in the case of ePOS EVM Use gptimer as clocksource instead, as is done in the case of AM335x (which does not have a SyncTimer). With this, system time keeping works accurately. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

ARM: OMAP2+: add missing lateinit hook for calling pm late init AM335x, AM43xx, OMAP5 and DRA7 have missing late init hook. Introduce SoC specific hook with a call to OMAP2+ generic lateinit hook. This allows the generic late initializations such as cpufreq hooks to be active. Based on out-of-tree patches that need to be introduced in mainline, this introduction allows us to provide the foundation for further SoC specific features as they are developed.
