From 9e264f3f85a56cc109cc2d6010a48aa89d5c1ff1 Mon Sep 17 00:00:00 2001 From: Amit Kumar Mahapatra via Alsa-devel Date: Fri, 10 Mar 2023 23:02:03 +0530 Subject: spi: Replace all spi->chip_select and spi->cs_gpiod references with function call MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod members of struct spi_device to be an array. But changing the type of these members to array would break the spi driver functionality. To make the transition smoother introduced four new APIs to get/set the spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and spi->cs_gpiod references with get or set API calls. While adding multi-cs support in further patches the chip_select & cs_gpiod members of the spi_device structure would be converted to arrays & the "idx" parameter of the APIs would be used as array index i.e., spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.
