Merge tag 'at91-fixes2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91 into fixes
Pull "Second fixes batch for AT91 on 4.0" from Nicolas Ferre: - little fix for !MMU debug: may also help for randconfig - fix of 2 errors in LCD clock definitions - in PM code, not writing the key leads to not execute the action * tag 'at91-fixes2' of git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91: ARM: at91/pm: MOR register KEY was missing ARM: at91/dt: sama5d4: fix lcdck clock definition ARM: at91/dt: sama5d4: rename lcd_clk into lcdc_clk ARM: at91: debug: fix non MMU debug
