From: Bartosz Golaszewski Date: Tue, 5 Feb 2019 13:03:44 +0000 (+0100) Subject: dt-bindings: at24: add the 'num-addresses' property X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e7224a116f0dac593233143849f25bc095f8d2cc;p=linux.git dt-bindings: at24: add the 'num-addresses' property Currently the at24 driver only creates additional i2c dummies for atmel,24c00 and it's hard-coded. Some other chips (like for example Microchip's 24AA02T) also take more slave addresses despite being otherwise compatible with already supported variants. Add a new property to the device tree binding document that defines the total number of i2c slave addresses taken by the device. The addresses are counted starting from the one in the reg property.
