Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx. Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y) Runtime-tested: bcm2708, bcm2710 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 128/454] panel-raspberrypi-touchscreen: Round up clk rate to
|
|
fix DSI panel.
|
|
|
|
Commit 488f9bc8e3def93e0baef53cee2026c2cb0d8956 slightly increased the
|
|
reported rate of PLLD, so the clk driver decided that PLLD/3/8 was now
|
|
higher than our requested pixel clock rate and rejected it in favor of
|
|
PLLD/4/8, which then ran the pixel clock way out of spec.
|
|
|
|
By bumping the requested clock rate just slightly, we get back to
|
|
PLLD/3/8 like we wanted and the panel displays content again.
