2017-03-22[media] media: vpif: use a configurable i2c_adapter_id for vpif displayBartosz Golaszewski1-0/+1
The vpif display driver uses a static i2c adapter ID of 1 but on the da850-evm board in DT boot mode the i2c adapter ID is actually 0. Make the adapter ID configurable like it already is for vpif capture.

This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added.

There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff.

2017-01-02ARM: davinci: da8xx: Fix sleeping function called from invalid contextAlexandre Bailon1-19/+15
Everytime the usb20 phy is enabled, there is a "sleeping function called from invalid context" BUG. In addition, there is a recursive locking happening because of the recurse call to clk_enable(). clk_enable() from arch/arm/mach-davinci/clock.c uses spin_lock_irqsave() before to invoke the callback usb20_phy_clk_enable(). usb20_phy_clk_enable() uses clk_get() and clk_enable_prepapre() which may sleep. Replace clk_prepare_enable() by davinci_clk_enable().

2017-01-02ARM: davinci: Make __clk_{enable,disable} functions publicAlexandre Bailon2-6/+8
In some cases, there is a need to enable a clock as part of clock enable callback of a different clock. For example, USB 2.0 PHY clock enable requires USB 2.0 clock to be enabled. In this case, it is safe to instead call __clk_enable() since the clock framework lock is already taken. Calling clk_enable() causes recursive locking error. A similar case arises in the clock disable path. To enable such usage, make __clk_{enable,disable} functions publicly available outside of clock.c. Also, call them davinci_clk_{enable|disable} now to be consistent with how other davinci-specific clock functions are named. Note that these functions are not exported to drivers. They are meant for usage in platform specific clock management code.

2017-01-02ARM: davinci: da850: fix da850_set_pll0rate()Bartosz Golaszewski1-4/+18
This function is confusing - its second argument is an index to the freq table, not the requested clock rate in Hz, but it's used as the set_rate callback for the pll0 clock. It leads to an oops when the caller doesn't know the internals and passes the rate in Hz as argument instead of the cpufreq index since this argument isn't bounds checked either. Fix it by iterating over the array of supported frequencies and selecting a one that matches or returning -EINVAL for unsupported rates. Also: update the davinci cpufreq driver. It's the only user of this clock and currently it passes the cpufreq table index to clk_set_rate(), which is confusing. Make it pass the requested clock rate in Hz.

2016-11-01ARM: davinci: da850: Fix pwm name matchingDavid Lechner2-8/+50
This fixes pwm name matching for DA850 familiy devices. When using device tree, the da850_auxdata_lookup[] table caused pwm devices to have the exact same name, which caused errors when trying to register the devices. We cannot have multiple entries for the same clock in in da850_clks[], so we have added child clocks to the EHRPWM and ECAP LPSC clocks so that each PWM device will have its own clock for proper name matching.

2016-11-01ARM: davinci: da8xx: register USB PHY clocks in the DT fileAxel Haslam1-0/+11
The usb20_phy clock needs to be registered for the driver to be able to get and enable a clock. Currently the usb phy clocks are registered from board files, which will not be called during a device tree based boot. To be able to probe correctly usb form a device tree boot, register the usb phy clocks from the DT specific init. Unfortunately, davinci does not have proper clock support on device tree yet, so by registering the clock from the DT specific file we are forced to hardcode the parent clock, and cannot select refclkin as parent for any of the phy clocks of the da850 family. As none of the current da850 based boards currently in mainline use refclkin as source. I guess we can live with this limitation until clocks are correctly represented through CCF/device tree.

Up to this point, the USB phy clock configuration was handled manually in the board files and in the usb drivers.

Also, the related code is removed from the board files and replaced with the new clock registration functions. This also removes the #if IS_ENABLED(CONFIG_USB_MUSB_HDRC) around the musb declaration and renames the musb platform device so that we can reference it from the usb20 clock even if the musb device is not used.

2016-10-31ARM: davinci: da8xx: Add full regulator constraints for non-DT bootAxel Haslam2-0/+6
The phy framework requests an optional "phy" regulator. If it does not find one, it returns -EPROBE_DEFER. In the case of non-DT boot for the omap138-lcdk board, this would prevent the usb11 phy to probe correctly and ohci would not enumerate. By calling regulator_has_full_constraints(), An error would be returned instead of -EPROBE_DEFER for the regulator, and the probe of the phy driver can continue normally without a regulator.

The CFGCHIP registers are used by a number of devices, so use a syscon device to share them. The first consumer of this will be the phy-da8xx-usb driver. Add the syscon device and register it.

Notably, an ongoing treewide effort to fix warnings caused by an update to the device tree compiler. These are enabled with "make W=1" at the moment but can hopefully become the default once all issues have been addressed.

2016-08-23ARM: davinci: da850: Add ti-aemif lookup for clock matchingKarl Beldan2-0/+2
The davinci boards don't have their clocks in DT yet and getting a clock will fail, unless registering them as clk_lookups. This registers the aemif clock for the ti-aemif memory driver. The current aemif lookup entry resolving to the same clock: 'CLK(NULL, "aemif", &aemif_clk)' is currently used by davinci_nand and remains for non-DT and backward compatibility. Currently the davinci boards only configure the AEMIF in case of non-DT boot, via some code in mach-davinci. This change will allow DT-based davinci platforms to do the same, via the ti-aemif memory driver code.

2016-08-09ARM: dts: da850: Add basic DTS for the LCDKKarl Beldan1-0/+1
The LCDK is the successor to the late Hawkboard. Among the differences are the flash (16bits vs 8bits) and some pins (MMC, LEDs, buttons, some external connectors), however the main components remain the same (eth. phy, audio codec, video decoder and DAC) except for the main PMIC, different and hard-wired on the LCDK (the LDOs and DCDCs are always on). A DT-only boot with this addition gives functional UART, reboot via watchdog, RTC, ethernet and MMC (I added the CD GPIO for the MMC although davinci_mmc doesn't call the OF facilities of mmc core).
