- 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 447/454] tpm: Make SECURITYFS a weak dependency
+
+commit 2f7d8dbb11287cbe9da6380ca14ed5d38c9ed91f upstream.
+
+While having SECURITYFS enabled for the tpm subsystem is beneficial in
+most cases, it is not strictly necessary to have it enabled at all.
+Especially on platforms without any boot firmware integration of the TPM
+(e.g. raspberry pi) it does not add any value for the tpm subsystem,
+as there is no eventlog present.
+
+By turning it from 'select' to 'imply' it still gets selected per
+default, but enables users who want to save some kb of ram by turning
+SECURITYFS off.
