- 950-0421-HID-hid-bigbenff-driver-for-BigBen-Interactive-PS3OF.patch
- 950-0453-Add-hid-bigbenff-to-list-of-have_special_driver-for-.patch

Make I2C built-in instead of modular as in upstream defconfig; also the
easiest way to get MFD_ARIZONA enabled, which is required by
kmod-sound-soc-rpi-cirrus.
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

+Subject: [PATCH 229/454] ASoC: pcm512x: implement set_tdm_slot interface
+
+PCM512x can accept data padded with additional BCLK cycles
+but the driver currently lacks an interface to configure this.
+
+This leads to the problem that S24_LE format in master mode
+can result in non-integer clock divisors and pcm512x running
+at a rather off rate.
+
+For example 48kHz with 48fs BCLK and SCLK at 24.576MHz uses
+a divisor of 10 (rounded down from 10.6666) and results in a
+51.2kHz LRCLK. With 64fs BCLK a divisor of 8 is used and
+LRCLK runs at exactly 48kHz.
+
+Fix this by providing a minimal set_tdm_slot implementation
+so machine drivers can optionally configure custom BCLK ratios.
