Subject: [RESEND PATCH 6/6] mfd: ti_am335x_tscadc: drop the CNTRLREG_8WIRE macro
Date:   Sun,  7 Nov 2021 12:22:36 +0100
Message-Id: <20211107112236.7969-7-dariobin@libero.it>
In-Reply-To: <20211107112236.7969-1-dariobin@libero.it>
References: <20211107112236.7969-1-dariobin@libero.it>
Precedence: bulk

In TI's reference manual description for the `AFE_Pen_Ctrl' bit-field
of the TSC's CTRL register, there is no mention of 8-wire touchscreens.
Even commit f0933a60d190 ("mfd: ti_am335x_tscadc: Update logic in CTRL
register for 5-wire TS") says that the value of this bit-field must be
the same for 4-wire and 8-wire touchscreens. So let's remove the
CNTRLREG_8WIRE macro to avoid misunderstandings.
