This patch introduces sh7372_late_devices which should include all regular processor specific platform devices. Early platform devices for console and timers should be put on the sh7372_early_devices list, all other devices should be on sh7372_late_devices.

2010-09-16fbdev: sh_mobile_lcdc: reconfigure the framebuffer, when freeGuennadi Liakhovetski2-1/+114
Currently the sh_mobile_lcdc driver only reconfigures the hardware interface, when a new monitor is plugged in. This patch adds support for dynamic framebuffer reconfiguration, when no user is holding the framebuffer device node open.

2010-09-14ARM: mach-shmobile: ap4evb: modify touchpanel judgment conditionKuninori Morimoto1-3/+35
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. This patch solve these issues Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14ARM: mach-shmobile: add two more video modes for HDMIGuennadi Liakhovetski1-6/+35

2010-09-14fbdev: sh_mobile_hdmi: support hot-plugging of different HDMI / DVI displaysGuennadi Liakhovetski2-64/+170
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: improve HDMI PHY parameters for high resolutionsGuennadi Liakhovetski1-2/+2
High monitor resolutions also require higher clock frequencies, current HDMI PHY parameters do not work well for resolutions higher than 720p. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>

2010-09-14fbdev: sh_mobile_lcdcfb: separate display variable data from framebuffer dataGuennadi Liakhovetski3-19/+27
This is a preparation for a patch, that shall allow displaying of a smaller framebuffer on a bigger display and of a part of a bigger framebuffer on a smaller display. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14fbdev: sh_mobile_hdmi: implement lockingGuennadi Liakhovetski4-47/+141
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 Liakhovetski1-1/+12
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. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14fbdev: sh_mobile_hdmi: add initial support for modes, other than 720pGuennadi Liakhovetski1-20/+62
To support standard video modes, other than 720p, the HDMI PHY configuration has to be adjusted and the VIC has to be sent to the display. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14fbdev: sh_mobile_lcdcfb: allocate memory, sufficient for the biggest modeGuennadi Liakhovetski1-6/+20
Now, that we add support for multiple modes to the sh_mobile_lcdcfb driver, it has to allocate memory, sufficient for the biggest of them. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14fbdev: sh_mobile_lcdcfb: fix notifier callback return codesGuennadi Liakhovetski1-6/+8
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. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
2010-09-14fbdev: sh_mobile_lcdcfb: Support multiple video modes in platform dataGuennadi Liakhovetski10-157/+219
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 Liakhovetski1-2/+2
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 Liakhovetski1-20/+3
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 <[email protected]> Signed-off-by: Paul Mundt <[email protected]>
