From mboxrd@z Thu Jan 1 00:00:00 1970 From: geert+renesas@glider.be (Geert Uytterhoeven) Date: Wed, 30 May 2018 17:25:10 +0200 Subject: [PATCH 0/6] ARM: shmobile: rcar: Drop lehacy SYSC fallbacks Message-ID: <1527693916-11215-1-git-send-email-geert+renesas@glider.be> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Hi Simon, Magnus, When DT SYSC support was introduced in v4.7, legacy fallbacks were kept to keep secondary CPUs working on R-Car H1, H2, and M2-W using old DTBs. However, the time has come to drop these fallbacks, and clean up the resulting code. Most of this was written when I worked on DT SYSC support, but postponed until the time was ripe. So basically I've been running this during the last +2 years. I avoided touching drivers/soc/renesas and arch/arm/mach-shmobile code in the same patch. If you prefer some patches to be squashed, please let me know. Tested on Marzen (R-Car H1), Lager (R-Car H2), and Koelsch (R-Car M2-W). Thanks!
