2012-01-27ARM: SAMSUNG: Fix missing api-change from subsys_interface changeHeiko Stuebner
Commit 4a858cfc9a (arm: convert sysdev_class to a regular subsystem) converted the samsung sysdevs into subsys_interface instances. While the original add-function only had a (struct sys_device *) parameter, the dev_add from subsys_interface needs (struct device *, struct subsys_interface *) leading to "initialized from incompatible pointer type" warnings.

2012-01-27ARM: SAMSUNG: Fix platform data setup for I2C adapter 0Sylwester Nawrocki
The common static default_i2c_data structure gets bus_num set by each s3c_i2c?_set_platdata() call, except for s3c_i2c0_set_platdata(). Thus if for instance s3c_i2c1_set_platdata() is called prior to s3c_i2c0_set_platdata() the I2C0 controller has bus_num set to wrong value of 1, i.e. the one from previous set_platdata call.

2012-01-27ARM: S3C6410: Use device names for both I2C clocksMark Brown
When the S3C64xx CPUs were converted to clkdev mappings were added for the I2C controllers on them. On S3C6410 a device name is specified for I2C controller 1 but not for controller 0 which makes the code less robust as we'll falsely return the clock for controller 0 if there's an error in the request for controller 1. Improve things by registering a device name for controller 0 as well. Due to the fact that we change the numbering for controller 0 depending on if we've registered controller 1 this requires an ifdef to choose the name.

2012-01-26ARM: OMAP: fix MMC2 loopback clock handlingGrazvydas Ignotas
Currently MMC2 setup code can only enable loopback clock and relies on reset value for boards that need to have it disabled. This causes a problem with certain bootloaders that always enable that clock, resulting with unwanted bootloader dependencies. Fix this by making it disable the clock if board data says so.

2012-01-26ARM: OMAP: fix erroneous mmc2 clock change on mmc3 setupGrazvydas Ignotas
hsmmc23_before_set_reg() can set MMCSDIO2ADPCLKISEL bit, which enables internal clock for MMC2. 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.

2012-01-26ARM: OMAP2+: timer: Fix crash due to wrong arg to __omap_dm_timer_read_counterVaibhav Hiremath
Commit 2f0778af (ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime) had a typo for the case when CONFIG_OMAP_32K_TIMER is not set. 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.

2012-01-26OMAPDSS: HDMI: PHY burnout fixTomi Valkeinen
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>

2012-01-25ARM: OMAP3: hwmod data: register dss hwmods after dss_coreIlya Yanok
dss_core has to be initialized before any other DSS hwmod. 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.
