| * ARM: OMAP2+: Limit omap_read/write usage to legacy USB driversTony Lindgren2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers should no longer use omap_read/write functions but instead use ioremap + read/write functions. As some USB legacy code is still shared between omap1 and omap2420, let's limit the omap_read/write to plat/usb.h. Note that the long term fix is to update the drivers to use ioremap and read/write functions. That can now be done as a separate patch series that is limited to the USB drivers. Also make sure the legacy omap1-keypad.c driver builds if selected for 2420 based systems. Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
| * ARM: OMAP: Remove plat/io.h by splitting it into mach/io.h and mach/hardware.hTony Lindgren2012-02-24
| | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to minimize io.h so the SoC specific io.h for ARMs can removed. Note that minimal driver changes for DSS and RNG are needed to include cpu.h for SoC detection macros.

| | | | | | | | | | | | | | | | | | | | | | | | There's no need to have these defines in plat/io.h. Note that we now need to ifdef omap_read/write calls as they will be available for omap1 only.

| | * OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen2012-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board if the HDMI PHY is kept powered on when the cable is not connected. This patch solves the problem by adding hot-plug-detection into the HDMI IP driver. This is not a real HPD support in the sense that nobody else than the IP driver gets to know about the HPD events, but is only meant to fix the HW bug. The strategy is simple: If the display device is turned off by the user, the PHY power is set to OFF. When the display device is turned on by the user, the PHY power is set either to LDOON or TXON, depending on whether the HDMI cable is connected. The reason to avoid PHY OFF when the display device is on, but the cable is disconnected, is that when the PHY is turned OFF, the HDMI IP is not "ticking" and thus the DISPC does not receive pixel clock from the HDMI IP. This would, for example, prevent any VSYNCs from happening, and would thus affect the users of omapdss. By using LDOON when the cable is disconnected we'll avoid the HW bug, but keep the HDMI working as usual from the user's point of view. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

(depending on CPU vendor, MSR_EFER and cpuid) Because previous mentioned OSs may not engage corresponding syscall target-registers (STAR, LSTAR, CSTAR), they remain NULL and (non trapping) syscalls are leading to multiple faults and finally crashs. Depending on the architecture (AMD or Intel) pretended by guests, various checks according to vendor's documentation are implemented to overcome the current issue and behave like the CPUs physical counterparts.

Currently this is broken as dss_core is listed in chip/revision specific hwmod lists while other DSS hwmods are listed in common list which is registered first. This patch moves DSS hwmods (except for dss_core) to the separate list which is registered last to ensure that dss_core is already registered. This solves the problem with BUG() in L3 interrupt handler on boards with DSS enabled in bootloader. The long-term fix to this is to ensure modules are set up in dependency order in the hwmod core code.

Currently this function is also called by code handling MMC3, and if .internal_clock is set in platform data (by default it currently is), it will set MMCSDIO2ADPCLKISEL for MMC2 instead of MMC3 (MMC3 doesn't have such bit so nothing actually needs to be done). This breaks 2nd SD slot on pandora. Fix this by changing hsmmc23_before_set_reg() to only handle MMC2. Note that this removes .remux() call for MMC3, but no board currently needs it and it's also not called for MMC4 and MMC5.

In dmtimer_read_sched_clock(), wrong argument was getting passed to __omap_dm_timer_read_counter() function call; instead of "&clksrc", we were passing "clksrc.io_base", which results into kernel crash. To reproduce kernel crash, just disable the CONFIG_OMAP_32K_TIMER config option (and DEBUG_LL) and build/boot the kernel.
