From cbae1a350e3ceff38242a4905805c80ccbcfbba5 Mon Sep 17 00:00:00 2001 From: Andreas Pape Date: Fri, 1 Mar 2024 09:50:03 +0100 Subject: ASoC: rcar: adg: correct TIMSEL setting for SSI9 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Timing select registers for SRC and CMD are by default referring to the corresponding SSI word select. The calculation rule from HW spec skips SSI8, which has no clock connection. >From section 43.2.18 CMD Output Timing Select Register (CMDOUT_TIMSEL), of R-Car Series, 3rd Generation Hardware User’s Manual Rev.2.20: CMD0_OUT_DIVCLK_ Output Timing SEL [4:0] Signal Select B'0 0110: ssi_ws0 B'0 0111: ssi_ws1 B'0 1000: ssi_ws2 B'0 1001: ssi_ws3 B'0 1010: ssi_ws4 B'0 1011: ssi_ws5 B'0 1100: ssi_ws6 B'0 1101: ssi_ws7 B'0 1110: ssi_ws9 B'0 1111: Setting prohibited Fix the erroneous prohibited setting of timsel value 1111 (0xf) for SSI9 by using timsel value 1110 (0xe) instead. This is possible because SSI8 is not connected as shown by in the table above. [21.695055] rcar_sound ec500000.sound: b adg[0]-CMDOUT_TIMSEL (32):00000f00/00000f1f Correct the timsel assignment.
