2012-01-12ccxmx53: da9052 tsi, do not control LDO9.Alex Gonzalez
On the ccxmx53, LDO9 is not supplying the touch. LDO8 is, but it also supplies other elements. Do not allow the touch driver to modify power supply settings as this assumes the touch is powered exclusively by a regulator while on the ccxmx53 it is not the case.

2012-01-11ccxmx53: da9053, set PERI regulator voltage.Alex Gonzalez
In old PMIC versions the PERI regulator had a variable step voltage values range. Recent PMICs, including in all Digi modules, have a fix 25mv step size, so remove the code that handled the variable step. We don't have revision information from Dialog to ascertain when the change happens, so we assume all supported PMICs are the new version. Signed-off-by: Alex Gonzalez <alex.gonzalez@digi.com>
2012-01-11ccxmx5x: change ccxmx53 pmic i2c addr and add devices_ccxmx5xPedro Perez de Heredia
This commit changes the i2c address of the pmic (0x68 on the third spin of the hardware). It also adds a new file devices_ccxmx5x.[c,h] to place common ccxmx51 and ccxmx53 initialization code. Signed-off-by: Pedro Perez de Heredia <pedro.perez@digi.com>

2012-01-03ccxmx53: da9052-rtc, revert a hunk from previous commitAlex Gonzalez
This commit reverts a single line hunk that got mixed with a different patch and pushed by mistake. It causes the da9052 drivers to crash when the I2C IMX module is loaded instead of being built in. Signed-off-by: Alex Gonzalez <alex.gonzalez@digi.com>
2012-01-03ccxmx53: da9052-tsi, disable window filter.Alex Gonzalez
The driver enables by default a window filter that stops tracking movement if it detects a pixel difference of 50 pixels between positions. Disabling this "feature" fixes this Vantive. This commit allows for the driver to be configured to use the window or not, with the default being to disable it. Signed-off-by: Alex Gonzalez <alex.gonzalez@digi.com>

2011-12-29mxc_ipuv3_fb3: fix problem with overlay and dual head (#40054)Pedro Perez de Heredia
This commit fixes a problem with the overlay and the dual-head support. The problem was related with the first initializtion of the overlay framebuffer and was caused by a previous work- arround that was done to support the dual-head video mode. Fixes #40054.

2011-12-28ccxmx5x dual video: remove code to make it workPedro Perez de Heredia
This code skips the execution of some code in the mxc_ipuv3_fb driver when dual head is used. This code was causing that the dual head was not working. This patch was implemented time ago for the wimx51 but had been lost while merging recent patches from FSL. It is not clear why we need this. Needs to be investigated.

2011-12-27ccxmx53: Add custom battery driverAlex Gonzalez
This battery driver is based on the da9052-battery.c driver by Dialog, and on the DVT battery scripts specific to the CCXMX53 JSK. The following limitations apply: - No battery temperature measurements are possible on the CCXMX53 JSK. - No events notifications are implemented. - No junction temperature or battery temperature monitoring. - VBUS charging not supported by JSK. - The only battery technology supported is Lithium-Ion. - Only standard working temperatures are supported.

2011-12-23ccxmx5x: add power_off supportPedro Perez de Heredia
Not that the implementation differs from the one from FSL. This one is similar to what we have implemented in WinCE. The procedure comes directly from Dialog. We dont know why the method used by FSL in their QSB it doesnt work in our module. She the comments in the code for additional details. Signed-off-by: Pedro Perez de Heredia <pedro.perez@digi.com>
2011-12-21ccxmx5x ipu_disp: Fix problem of 1 pixel shifted and fuzzy VGAPedro Perez de Heredia
This commit implements a workarround to avoid that the video output is shifted 1 pixel to the right. This happens when the original code from FSL (after applying a patch) and has been also observed in their Evaluation Board. Their fix tries to correct a fuzzy VGA output. In order to get the best video output we only apply the new code when the configured output is the VGA interface. This is the best fix I can implement at this point. This is the video controller microcode and I dont know what they are exactly doing in each configuration. We have to check with FSL for a better fix.

- Fixed PxP input left coordinate value. Was previously being incorrectly computed such that the value would be incorrect when using 16bpp RGB and an X coordinate that is offset from 4-pixel alignment by 1 (e.g. x=1, x=5). The resulting effect was that updates meeting this criteria would be drawn to the EPD panel shifted to the right by 1 pixel. Signed-off-by: Danny Nold <dannynold@freescale.com>

2011-12-15ENGR00152560 [MX233/MX28]mxs-mmc: fix clock rate settingTony Lin
Fix clock rate setting on mxs-mmc driver. Previously, if div2 was zero the value for TIMING_CLOCK_RATE would have been 255 instead of 0. Also the limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE + 1) where not correctly defined. Can easily be reproduced on mx23evk: default clock for high speed sdio cards is 50 MHz. With a SSP_CLK of 28.8 MHz (default), this resulted in an actual clock rate of about 56 kHz. Signed-off-by: Tony Lin <tony.lin@freescale.com>

2011-12-15ENGR00151896 - EPDC fb: Fix bug preventing suspend when powerdown disabledDanny Nold
- With FB_POWERDOWN_DISABLE is set as the powerdown delay (disabling the EPDC driver from powering down), the EPDC driver was having problems going into suspend. Any request to blank the EPDC driver would result in a timeout and an error status. And subsequent attempts to send updates to the driver would fail, as the driver's power state was incorrect. This patch prompts the EPDC driver to be disabled when the blanking state is changed to FB_BLANK_POWERDOWN and FB_POWERDOWN_DISABLE is set. Resultingly, the correct driver power state is maintained and suspend/resume works correctly. Signed-off-by: Danny Nold <dannynold@freescale.com>
2011-12-15ENGR00144112 TVE:Fix potential hang issue for suspendLiu Ying
Framebuffer suspend event comes before framebuffer blank event when system entering suspend mode. So, if another driver calls FB_EVENT_BLANK notifier chain, i.e, Android IPUv3 fb driver, the suspend and blank event handlers registered in TVE driver will be called. We used to disable TVE clock in suspend handler, so it causes system hang when we try to access TVE register when go to blank handler. This patch fixes this issue.

Also if the driver found MMC_PM_WAKE_SDIO_IRQ in pm_flags, it should not unregister irq of this host, since the client maybe use this irq to support wake up.
