+Subject: drm/meson: Correct OSD1 global alpha value
+
+From: Stuart Menefy <stuart.menefy@mathembedded.com>
+
+[ Upstream commit 6836829c8ea453c9e3e518e61539e35881c8ed5f ]
+
+VIU_OSD1_CTRL_STAT.GLOBAL_ALPHA is a 9 bit field, so the maximum
+value is 0x100 not 0xff.
+
+This matches the vendor kernel.

+[ Upstream commit 279c12df8d2efb28def9d037f288cbfb97c30fe2 ]
+
+Commit e39d5ef67804 ("powerpc/5xxx: extend mpc8xxx_gpio driver to support
+mpc512x gpios") implemented support for IRQ_TYPE_LEVEL_LOW flow type in
+mpc512x via falling edge type. Do same for mpc85xx which support was added
+in commit 345e5c8a1cc3 ("powerpc: Add interrupt support to mpc8xxx_gpio").
+
+Fixes probing of lm90 hwmon driver on mpc85xx based board which use level
+interrupt. Without it kernel prints error and refuse lm90 to work:
+
+ [ 15.258370] genirq: Setting trigger mode 8 for irq 49 failed (mpc8xxx_irq_set_type+0x0/0xf8)
+ [ 15.267168] lm90 0-004c: cannot request IRQ 49
+ [ 15.272708] lm90: probe of 0-004c failed with error -22
