From: Shengjiu Wang Date: Thu, 10 Jul 2025 03:04:04 +0000 (+0800) Subject: ASoC: fsl_xcvr: get channel status data when PHY is not exists X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca592e20659e0304ebd8f4dabb273da4f9385848;p=thirdparty%2Fkernel%2Flinux.git ASoC: fsl_xcvr: get channel status data when PHY is not exists There is no PHY for the XCVR module on i.MX93, the channel status needs to be obtained from FSL_XCVR_RX_CS_DATA_* registers. And channel status acknowledge (CSA) bit should be set once channel status is processed.
