2013-10-18pwm-backlight: Fix brightness adjustmentThierry Reding1-12/+18
Split adjustment of the brightness (by changing the PWM duty cycle) from the power on sequence. This fixes an issue where the brightness can no longer be updated once the backlight has been enabled. Reported-by: Marc Dietrich <marvin24@gmx.de> Signed-off-by: Thierry Reding <treding@nvidia.com>

2013-10-17video: exynos_dp: remove non-DT support for Exynos Display PortJingoo Han4-94/+135
Exynos Display Port can be used only for Exynos SoCs. In addition, non-DT for EXYNOS SoCs is not supported from v3.11; thus, there is no need to support non-DT for Exynos Display Port. The 'include/video/exynos_dp.h' file has been used for non-DT support and the content of file include/video/exynos_dp.h is moved to drivers/video/exynos/exynos_dp_core.h. Thus, the 'exynos_dp.h' file is removed. Also, 'struct exynos_dp_platdata' is removed, because it is not used any more.

2013-10-16pwm-backlight: Allow for non-increasing brightness levelsMike Dunn1-14/+15
Currently the driver assumes that the values specified in the brightness-levels device tree property increase as they are parsed from left to right. But boards that invert the signal between the PWM output and the backlight will need to specify decreasing brightness-levels. This patch removes the assumption that the last element of the array is the maximum value, and instead searches the array for the maximum value and uses that in the duty cycle calculation.

2013-10-16pwm-backlight: Add power supply supportThierry Reding1-0/+13
Backlights require a power supply to work properly. This commit adds a regulator to power up and power down the backlight. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-16pwm-backlight: Use new enable_gpio fieldThierry Reding1-7/+50
Make use of the new enable_gpio field and allow it to be set from DT as well. Now that all legacy users of platform data have been converted to initialize this field to an invalid value, it is safe to use the field from the driver. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-16pwm-backlight: Track enable stateThierry Reding1-0/+11
Follow up patches will add support for more complex means of powering the backlight on and off such as using a regulator. To prevent calls to the regulator API from becoming unbalanced, keep track of the enabled state internally. Signed-off-by: Thierry Reding <treding@nvidia.com>
2013-10-16pwm-backlight: Refactor backlight power on/offThierry Reding1-22/+31

2013-10-16backlight: introduce backlight_device_registeredAaron Lu1-0/+31
Introduce a new API for modules to query if a specific type of backlight device has been registered. This is useful for some backlight device provider module (e.g. ACPI video) to know if a native control interface(e.g. the interface created by i915) is available and then do things accordingly (e.g. avoid registering its own on Win8 systems).

2013-10-09hyperv-fb: add pci stubGerd Hoffmann1-1/+39
This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer driver will bind to the pci device then, so linux kernel and userspace know there is a proper kernel driver for the device active. lspci shows this for example: [root@dhcp231 ~]# lspci -vs8 00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual VGA (prog-if 00 [VGA controller]) Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at f8000000 (32-bit, non-prefetchable) [size=64M] Expansion ROM at <unassigned> [disabled] Kernel driver in use: hyperv_fb Another effect is that the xorg vesa driver will not attach to the device and thus the Xorg server will automatically use the fbdev driver instead.

2013-10-09omapdss: HDMI: Use OMAP4 HDMI core functions directly and remove hdmi_ip_opsArchit Taneja6-184/+162
After removing wrapper, pll and phy funcs from ti_hdmi_4xxx_ip.c, we are left with OMAP4 HDMI core functions. Use these directly in hdmi.c rather than using hdmi_ip_ops. Rename the core functions with a 'hdmi4' suffix. We used to have hdmi_ip_ops so that one could support HDMI within a TI SoC which had a non-DSS display subsytem. This however never got put into use, and hence these ops aren't useful any more. The DT/hwmod information for hdmi doesn't split the address space according to the required sub blocks. Keep the address offset and size information in the driver for now. This will be removed when the driver gets the information correctly from DT/hwmod.

These will be shared amongst the omap4/5 hdmi platform drivers. Remove the PHY function pointer ops from the ti_hdmi_ip_ops struct.

HDMI wrapper is a block common to DSS in OMAP4, OMAP5 and DRA7x. Move the existing functions from ti_hdmi_4xxx_ip.c to a separate file.

Move some of the enums, structs and funcs related to the wrapper from ti_hdmi_4xxx_ip.h to ti_hdmi.h. These will be shared amongst the omap4/5 hdmi platform drivers and other libraries. The old hdmi_wp_init() is removed since it didn't do anything. Timing parameters like interlace, hsync_level and vsync_level weren't copied correctly before. Those are copied correctly now.
