| * OMAPDSS: DSI: fix depopulating dsi peripheralsTomi Valkeinen2014-08-081-8/+1Star
| | | | | | | | | | | | | | | | | | | | After v3.16-rc1, devices populated with of_platform_populate() should be depopulated using of_platform_depopulate(). Failure to do so prevents the devices from being populated again (e.g. when loading a module). This patch fixes the problem for the OMAP DSI driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the omapdrm driver use the new HDMI ops when possible. omapdrm will call set_hdmi_mode (when available) to tell the encoder driver whether the monitor is a DVI or HDMI monitor, and if it's an HDMI monitor, omapdrm will call set_hdmi_infoframe to to set the AVI infoframe.

As a result, the VM Connection window can't refresh until it's closed and we re-connect to the VM. We can register a handler on panic_notifier_list: the handler can notify the VSC and switch the framebuffer driver to a "synchronous mode", meaning the VSC flushes any future framebuffer change to the VSP immediately. v2: removed the MS-TFS line in the commit message v3: remove some 'unlikely' markings v4: avoid global variables as Tomi Valkeinen suggested Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Dexuan Cui <decui@microsoft.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The .config() hook imx_pwm_config() calls clk APIs like clk_prepare() and clk_get_rate(), which might sleep, so we need to set can_sleep flag on pwm_chip.

| * | pwm: lpss: remove dependency on clk frameworkHeikki Krogerus2014-08-071-22/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike other Intel LPSS devices, the PWM does not have the clock dividers or the gate. All we get from the clock is the rate. Since PCI case uses the driver data to get the rate, we can drop the clk and use the same data also in case of ACPI. The frequency is the same.
