2010-10-15ARM: mach-shmobile: add TMU platform data for sh7372Magnus Damm
This patch adds support for the two first channels of the TMU0 timer block on sh7372. One channel is used for clock event, the other for clock source.

2010-10-15fbdev: sh_mobile_hdmi: add support for the "video=" kernel command line optionGuennadi Liakhovetski
Add support for specifying video modes on the kernel command line. Mode selection priorities are also changed such, that only exact matches of specified modes with monitor modes from EDID are accepted, at least in width and height. If none found - fall back to framebuffer default setting, if available. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-10-15ARM: mach-shmobile: remove videomodes from ap4evb platform dataGuennadi Liakhovetski
Now that HDMI videomodes have become optional, they can be safely removed from ap4evb platform data, since anyway 720p seems to be the best supported mode. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-15fbdev: sh_mobile_lcdc: make platform videomode table optionalGuennadi Liakhovetski
Add a default 720p mode to the sh_mobile_lcdc driver to be used, when no videomode is specified in the platform data. This can be used, e.g., with HDMI. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This patch introduces sh7372_late_devices which should include all regular processor specific platform devices.

2010-09-16fbdev: sh_mobile_lcdc: reconfigure the framebuffer, when freeGuennadi Liakhovetski
Currently the sh_mobile_lcdc driver only reconfigures the hardware interface, when a new monitor is plugged in.

2010-09-14ARM: mach-shmobile: ap4evb: modify touchpanel judgment conditionKuninori Morimoto
Current touchpanel had below 2 issues - LCDD2 pin which is needed for WVGA was changed to IRQ28_123 pin on ts_get_pendown_state - GPIO pull up on ts_init was disabled by gpio_request on ts_get_pendown_state. This mean the return value from gpio_get_value is untrusted.

2010-09-14fbdev: sh_mobile_hdmi: support hot-plugging of different HDMI / DVI displaysGuennadi Liakhovetski
With this patch hot-plugging of an HDMI or a DVI monitor can select a different video mode and reconfigure the LCDC and HDMI controllers accordingly. Due to a lack of a standard API to inform framebuffer users of a changed video mode, the framebuffer configuration is preserved regardless of a specific mode, selected for the monitor. As described in a previous patch, this leads to smaller framebuffers being displayed on larger monitors or a part of a larger framebuffer being displayed on a smaller resolution monitor.

2010-09-14fbdev: sh_mobile_hdmi: implement lockingGuennadi Liakhovetski
The SH-Mobile HDMI driver runs in several contexts: ISR, delayed work-queue, task context, when called from the sh_mobile_lcdc framebuffer driver. This creates ample race possibilities. Even though most these races are purely theoretical, it is better to close them. To trace fb_info validity we install a notification callback in the HDMI driver, and the only way for it to get to driver internal data is by using struct sh_mobile_lcdc_chan, therefore it had to be extracted into a separate common header.

2010-09-14fbdev: sh_mobile_hdmi: enable "external" modeGuennadi Liakhovetski
The SH-Mobile HDMI controller supports two configuration modes: using pre-programmed VICs and the "external" mode - specifying video parameters explicitly. The driver already contains code, necessary to configure HDMI manually, this patch actually enables it.

2010-09-14fbdev: sh_mobile_hdmi: add initial support for modes, other than 720pGuennadi Liakhovetski

2010-09-14fbdev: sh_mobile_lcdcfb: allocate memory, sufficient for the biggest modeGuennadi Liakhovetski

2010-09-14fbdev: sh_mobile_lcdcfb: fix notifier callback return codesGuennadi Liakhovetski
Notifier callbacks have to return either one of NOTIFY_* codes or a negative errno, converted to a suitable value by the notifier_from_errno() inline, if the notifier chain shall not be continued.

2010-09-14fbdev: sh_mobile_lcdcfb: Support multiple video modes in platform dataGuennadi Liakhovetski
This is a preparation for HDMI hotplug support. This patch just moves all platform defined video modes for the sh_mobile_lcdcfb driver to separate arrays and switches all users to use element 0 of that array, so, this patch doesn't introduce any functional changes and as such should not cause any regressions.

2010-09-14fbdev: sh_mobile_lcdcfb: fix more error pathsGuennadi Liakhovetski
This patch fixes the following two erroneous error paths: hw_usecnt is allocated with a value of 0, therefore in an early error case, calling sh_mobile_lcdc_clk_off() will wrongly conclude, that hw_usecnt has already been incremented. Then sh_mobile_lcdc_runtime_suspend() will be called, which will access uninitialised data fields and crash the kernel. sh_mobile_lcdc_stop() can be called before framebuffer has been allocated, then ch->info is NULL and dereferencing it will Oops too.

2010-09-14fbdev: sh_mobile_hdmi: simplify the EDID reading procedureGuennadi Liakhovetski
The present SH-Mobile HDMI driver reads and parses the EDID block into a variable screeninfo object, but since it is still unable to dynamically reconfigure the framebuffer, it overwrites the EDID information with preset values again. This patch just uses a temporary variable to store the EDID timing information instead. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
