2013-06-26video: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure, since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound). Thus, it is not needed to manually clear the device driver data to NULL.

2013-01-03Drivers: video: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-11-21fbdev: sh_mipi_dsi: Remove last reference to LCDC platform dataLaurent Pinchart
The format check that references LCDC platform data isn't needed, as the mismatch between LCDC and MIPI-DSI platform it detects would result in a badly displayed image, which isn't worse than a complete failure to setup the transmitter.

2012-03-21fbdev: sh_mipi_dsi: add extra phyctrl for sh_mipi_dsi_infoKuninori Morimoto
sh_mipi uses some clocks, but the method of setup depends on CPU. Current SuperH (like sh73a0) can control all of these clocks by CPG (Clock Pulse Generator). It means we can control it by clock framework only. But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS, and only sh7372 has PHYCTRL::PLLDS. But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was overwrote since the callback timing of clock setting was changed by c2658b70f06108361aa5024798f9c1bf47c73374 (fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()). To solve this issue, this patch adds extra .phyctrl. This patch adds detail explanation for unclear mipi settings and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

2011-11-21fbdev: sh_mipi_dsi: add VMLEN1/VMLEN2 calculationKuninori Morimoto
VMLEN1/VMLEN2 needs blanking length which is calculated from video image size. The calculation methods are explained on [SH MIPI] - [Video Mode] - [Blanking Packet setting] But HFPLEN (= VMLEN2) is un-understandable. For example, if SH-MIPI input was RGB888 (3byte), output was RGB888 (3byte) and 3lane connection, the date goes straight. But if SH-MIPI input was RGB888 (3byte), output was RGB565 (2byte) and 4lane connection, it needs delay in HFPLEN. Then (input cycle - output cycle) * lane is necessary the delay Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
