2017-06-09rockchip: rk3288: Convert clock driver to use shifted masksSimon Glass
Shifted masks are the standard approach with rockchip since it allows use of the mask without shifting it each time. Update the definitions and the driver to match. Signed-off-by: Simon Glass <sjg@chromium.org>

2017-06-09rockchip: video: Add remove() methodsSimon Glass
Add remove() methods for EDP and VOP so that U-Boot can shut down the video on exit. This avoids leaving DMA running while booting Linux which can cause problems if Linux uses the frame buffer for something else. It also makes it clear what is needed to shut down video. While we are here, make rkvop_enable() static.

2017-06-08rockchip: video: rk3399: add HDMI TX support on the RK3399Philipp Tomsich
This commit enables the RK3399 HDMI TX, which is very similar to the one found on the RK3288. As requested by Simon, this splits the HDMI driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and a common portion (rk_hdmi.c). Note that the I2C communication for reading the EDID works well with the default settings, but does not with the alternate settings used on the RK3288... this configuration aspect is reflected by the driverdata for the RK3399 driver. Having some sort of DTS-based configuration for the regulator dependencies would be nice for the future, but for now we simply use lists of regulator names (also via driverdata) that we probe.

2017-06-08rockchip: video: split RK3288-specific part off from rk_hdmiPhilipp Tomsich
To prepare for the addition of RK3399 HDMI support, the HDMI driver is refactored and broken into a chip-specific and a generic part. This change adds the internal interfaces, makes common/reusable functions externally visible and splits the RK3288 driver into a separate file. For the probing of regulators, we reuse the infrastructure created during the VOP refactoring... i.e. we simply call into the helper function defined for the VOP.

2017-06-08rockchip: video: refactor rk_vop and split RK3288-specific code offPhilipp Tomsich
To prepare for adding the RK3399 VOP driver (which shares most of its registers and config logic with the RK3228 VOP), this change refactors the driver and splits the RK3288-specific driver off. The changes in detail are: - introduces a data-structure for chip-specific drivers to register features/callbacks with the common driver: at this time, this is limited to a callback for setting the pin polarities (between the VOP and the encoder modules) and a flag to signal 10bit RGB capability - refactors the probing of regulators into a helper function that can take a list of regulator names to probe and autoset - moves the priv data-structure into a (common) header file to be used by the chip-specific drivers to provide base addresses to the common driver - uses a callback into the chip-specific driver to set pin polarities (replacing the direct register accesses previously used) - splits enabling the output (towards an encoder) into a separate help function withint the common driver Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2017-06-07rockchip: efuse: add (misc) driver for RK3399 non-secure efuse blockPhilipp Tomsich
This adds a simple driver for reading the efuse block of the RK3399. It should be easy enough to add drivers for other devices (e.g. the RK3328, RK3368, etc.) by passing the device details via driver_data. Unlike the kernel driver (using the nvmem subsystem), we don't expose the efuse as multiple named cells, but rather as a linear memory that can be read using misc_read(...). The primary use case (as of today) is the generation of a 'serial#' (and a 'cpuid#') environment variable for the RK3399-Q7 (Puma) system-on-module. Note that this adds a debug-only (i.e. only if DEBUG is defined) command 'rk3399_dump_efuses' that dumps the efuse block's content. N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to include a SoC-name (together with a comment in the function) to remind whoever adds support for additional SoCs that this function currently makes assumptions regarding the size of the fuse-box based on the RK3399. The hope is that the function is adjusted to reflect any changes resulting from generalising the driver for multiple SoCs and is then renamed.

2017-06-05reset: sti: add deassert counter in reset channel descriptorPatrice Chotard
This deassert counter allow to manage "shared" reset lines encountered in some specific case. On STiH410 SoC, DWC3, EHCI and OHCI are all using a respective PHY, but all of these PHYs shared a "global" reset. Currently, during command "usb stop", all host controller are stopped (XHCI, EHCI and OHCI). XHCI is first shutdowned, which means that PHY global reset is asserted. Then EHCI is shutdowned, but its PHY reset has already been asserted which make handshake() call failed in ehci_shutdown(). This counter allows to really assert a reset lines only when the "last" user is asserting it. Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>
