Subject: input: ti_am33x_tsc: remove platform_data support
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b9194fdfa6e729b97ffc59ae00dc9d51c7ae314d;p=linux-beck.git

input: ti_am33x_tsc: remove platform_data support

This patch removes access to platform data mfd_tscadc_board because the
platform is DT only.
