From 9845217d60d01d151b45842ef2017a65e8f39f5a Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 12 Jul 2023 12:16:16 +0100 Subject: [PATCH] net: dsa: ar9331: Use explict flags for regmap single read/write The at9331 is only able to read or write a single register at once. The driver has a custom regmap bus and chooses to tell the regmap core about this by reporting the maximum transfer sizes rather than the explicit flags that exist at the regmap level. Since there are a number of problems with the raw transfer limits and the regmap level flags are better integrated anyway convert the driver to use the flags. No functional change.
