From 8f2242b91501f4510f63f400cf7dae61912c6fef Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Tue, 25 Aug 2020 22:17:43 +0200 Subject: [PATCH] spi: pxa2xx: Add SSC2 and SSPSP2 SSP registers Update list of SSP registers with SSC2 and SSPSP2. These registers are utilized by LPT/WPT AudioDSP architecture. While SSC2 shares the same offset (0x40) as SSACDD, description of this register for SSP device present on mentioned AudioDSP is different so define separate constant to avoid any ambiguity.
