2013-09-27ASoC: SAMSUNG: Add I2S soundcard using stub codecTushar Behera
HDMI can be configured to source audio data from I2S bus. For boards on which there are no external audio chips, we still need to create a I2S-based soundcard with a dummy codec driver to enable I2S subsystem to pump data to the I2S bus, which can be used by HDMI module.

2013-09-27ASoC: codec: i2s_stub: Add a dummy I2S based codec driverTushar Behera
HDMI (in Samsung EXYNOS based SoCs) can be configured to source audio data from I2S bus. For boards on which there are no external audio chips, we still need to create a I2S-based soundcard with a dummy codec driver to enable I2S subsystem to pump data to the I2S bus, which can be used by HDMI module. This patch adds a I2S stub audio codec driver which can be used to create a I2S soundcard when external chip is not there. Signed-off-by: Tushar Behera <tushar.behera@linaro.org>

2013-09-27drm/exynos: replace dummy hdmiphy clock with pmu register controlRahul Sharma
Previous to CCF, hdmiphy is added as a dummy clock in clock file for exynos SoCs. Enable/Disable to this clock, actually toggles the power control bit in PMU, instead of controlling the clock gate. Patch adds the support to parse hdmiphy control node which is a child node to hdmi, and map the pmu register to toggle the power control bit.

2013-09-27clk/exynos5250: add mout_hdmi mux clock for hdmiRahul Sharma
hdmi driver needs to change the parent of hdmi clock frequently between pixel clock and hdmiphy clock. hdmiphy is not stable after power on and for a short interval while changing the phy configuration. For this duration pixel clock is used to clock hdmi. This patch is exposing the mux for changing parent.

2013-09-27i2c: s3c2410 : Add polling mode supportVasanth Ananthan
This patch adds polling mode support for i2c-s3c2410 driver. The I2C_SATAPHY controller in exynos5250 lacks an interrupt line and the i2c-s3c2410 driver is only interrupt driven, thus a polling mode support is required in the driver for supporting this controller. This patch adds this support to the driver. The SATAPHY bus is an internal bus with I2C controller as master and SATA PHY controller as the slave.

2013-09-27ARM: EXYNOS: Set arch_sys_counter as default clocksourceTushar Behera
The Exynos 5250 includes an architected timer which is on core and very cheap to read. Enabling the architected timer can lead to a significant performance improvement for timer sensitive workloads such as TCP/IP. It turns out that both arch_sys_counter and mct-frc have a rating of 400. On bootup, arch_sys_counter is initialized first then the clocksource changes to mct-frc when that initialises later on. If the rating of mct-frc is reduced below 400, then arch_sys_counter becomes the default. Suggested-by: Steve Capper <steve.capper@linaro.org> Signed-off-by: Tushar Behera <tushar.behera@linaro.org>
2013-09-27ARM: EXYNOS: Fix hotplug when CPUs are booted in HYP modeInderpal Singh
In intial boot-up, u-boot commit "3d28a181aab5e... arndale5250: Boot in Hyp mode and enable architected timers" puts the CPUs in HYP mode. Hence, the CPUs need to be put in HYP mode when they are hot plugged out and plugged back in. This patch is almost same as above u-boot patch, it additionally takes care if the kernel is compiled with thumb-2 option.
