Message-ID: <1366342893.20735.0.camel@phoenix> Date: Fri, 19 Apr 2013 11:41:33 +0800 From: Axel Lin <axel.lin@...ics.com> To: Mark Brown <broonie@...nsource.wolfsonmicro.com> Cc: Laxman Dewangan <ldewangan@...dia.com>, Graeme Gregory <gg@...mlogic.co.uk>, Liam Girdwood <lgirdwood@...il.com>, linux-kernel@...r.kernel.org Subject: [PATCH RFT] regulator: palmas: Don't update tstep register for SMPS3 and SMPS7 SMPS3 and SMPS7 do not have tstep_addr setting, so current code actually writes 0 to PALMAS_SMPS12_CTRL(0x0) register when set_ramp_delay callback is called for SMPS3 and SMPS7.
