2021-05-28drm/rockchip: cdn-dp: fix sign extension on an int multiply for a u64 resultColin Ian King1-1/+1
The variable bit_per_pix is a u8 and is promoted in the multiplication to an int type and then sign extended to a u64. If the result of the int multiplication is greater than 0x7fffffff then the upper 32 bits will be set to 1 as a result of the sign extension. Avoid this by casting tu_size_reg to u64 to avoid sign extension and also a potential overflow.

2021-05-28drm/rockchip: dsi: remove extra component_del() callThomas Hebb1-4/+0
commit cf6d100dd238 ("drm/rockchip: dsi: add dual mipi support") added this devcnt field and call to component_del(). However, these both appear to be erroneous changes left over from an earlier version of the patch. In the version merged, nothing ever modifies devcnt, meaning component_del() runs unconditionally and in addition to the component_del() calls in dw_mipi_dsi_rockchip_host_detach(). The second call fails to delete anything and produces a warning in dmesg. If we look at the previous version of the patch[1], however, we see that it had logic to calculate devcnt and call component_add() in certain situations. This was removed in v6, and the fact that the deletion code was not appears to have been an oversight.

2021-05-28drm/rockchip: dsi: move all lane config except LCDC mux to bind()Thomas Hebb1-8/+28
When we first enable the DSI encoder, we currently program some per-chip configuration that we look up in rk3399_chip_data based on the device tree compatible we match. This data configures various parameters of the MIPI lanes, including on RK3399 whether DSI1 is slaved to DSI0 in a dual-mode configuration. It also selects which LCDC (i.e. VOP) to scan out from. This causes a problem in RK3399 dual-mode configurations, though: panel prepare() callbacks run before the encoder gets enabled and expect to be able to write commands to the DSI bus, but the bus isn't fully functional until the lane and master/slave configuration have been programmed. As a result, dual-mode panels (and possibly others too) fail to turn on when the rockchipdrm driver is initially loaded. Because the LCDC mux is the only thing we don't know until enable time (and is the only thing that can ever change), we can actually move most of the initialization to bind() and get it out of the way early. That's what this change does. (Rockchip's 4.4 BSP kernel does it in mode_set(), which also avoids the issue, but bind() seems like the more correct place to me.) Tested on a Google Scarlet board (Acer Chromebook Tab 10), which has a Kingdisplay KD097D04 dual-mode panel. Prior to this change, the panel's backlight would turn on but no image would appear when initially loading rockchipdrm. If I kept rockchipdrm loaded and reloaded the panel driver, it would come on. With this change, the panel successfully turns on during initial rockchipdrm load as expected.

2021-05-28drm/rockchip: remove existing generic drivers to take over the deviceJavier Martinez Canillas1-0/+10
There are drivers that register framebuffer devices very early in the boot process and make use of the existing framebuffer as setup by the firmware. If one of those drivers has registered a fbdev, then the fallback fbdev of the DRM driver won't be bound to the framebuffer console. To avoid that, remove any existing generic driver and take over the graphics device. By doing that, the fb mapped to the console is switched correctly from the early fbdev to the one registered by the rockchip DRM driver: [ 40.752420] fb0: switching to rockchip-drm-fb from EFI VGA Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Tested-by: Peter Robinson <pbrobinson@gmail.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210516074833.451643-1-javierm@redhat.com

device_get_next_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller.

There is no user of of*.h headers, but mod_devicetable.h. Update header block accordingly. Signed-off-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>
2021-05-28leds: lm36274: Put fwnode in error case during ->probe()Andy Shevchenko1-0/+1
device_get_next_child_node() bumps a reference counting of a returned variable. We have to balance it whenever we return to the caller. In the older code the same is implied with device_for_each_child_node().

2021-05-28leds: lm3532: Make error handling more robustAndy Shevchenko1-5/+2
It's easy to miss necessary clean up, e.g. firmware node reference counting, during error path in ->probe(). Make it more robust by moving to a single point of return. Signed-off-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>

Since GPIO operations are NULL-aware, we don't need to duplicate this check. Remove it and fold the rest of the code. Signed-off-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Pavel Machek <pavel@ucw.cz>
