Tizen modem utility and xmm626x modem uses old style modem I/F. I brought the driver from linux-3.0 kernel[1] because the driver should be matched with telephony and modem-util package. Kamil brought the driver from linux-3.4-exynos, but the driver didn't match the current telephony daemon and modem util. Data communication didn't work with the driver. So, I decided to regress to old driver. Tizen Modem Team doesn't have any plan to update latest version of modem package. To maintain consistency of the interface, I picked the driver from linux-3.0 tree.

2014-04-24phy: exynos4212-usb: Use refcount to power device PHY for HSIC0refs/changes/19/20019/1Tomasz Figa1-0/+10
HSIC0 requires device PHY to be powered up and the driver handles that already, but there is no reference counting of device PHY power state, so unplugging USB cable powers it down, breaking modem IF operation. This patch fixes the issue by adding handling of reference counting of device PHY to HSIC0 power-down/-up.

2014-04-08ASoC: Samsung: Do not queue cyclic buffers multiple timesrefs/changes/89/19189/1Tomasz Figa2-2/+18
The legacy S3C-DMA API required every period of a cyclic buffer to be queued separately. After conversion of Samsung ASoC to Samsung DMA wrappers somebody made an assumption that the same is needed for DMA engine API, which is not true. In effect, Samsung ASoC DMA code was queuing the whole cyclic buffer multiple times with a shift of one period per iteration, leading to: a) severe memory waste - up to 13x times more DMA transfer descriptors are allocated than needed, b) possible memory corruption, because further cyclic buffers were out of the original buffers, due to the offset. This patch fixes this problem by making the legacy S3C-DMA API use the same semantics as DMA engine (the whole cyclic buffer is enqueued at once) and modifying users of Samsung DMA wrappers in cyclic mode to behave appropriately.

s3c-rtc is not functioning - initializing its value on every boot. As registering rtc devices is non-deterministic, s3c-rtc may be registered under rtc0 and rtc0 is default device for setting and getting hardware time (hwclock). Another working rtc driver is enabled. Change-Id: I651da859db6ad9b35d422288845c0bebbcf540f5 Signed-off-by: Marcin Niesluchowski <m.niesluchow@samsung.com>
2014-04-03cpufreq:LAB: Change method of boost state preservingrefs/changes/01/18901/2Lukasz Majewski1-4/+5
It is not necessary to change the boost state when LAB governor is entered, since LAB will change it according to its own politics. Only enter state is preserved. When leaving the LAB, only when required, work is scheduled to restore boost initial state.

2014-04-03cpufreq:governor: Add serialization to the cpufreq_governor_dbs() functionrefs/changes/00/18900/2Lukasz Majewski1-2/+12
It is necessary to serialize access to cpufreq_governor_dbs() function, since it can be accessed from different, not protected by any mutex paths like sysfs boost attribute or LAB governor internals.
