Subject: [U-Boot] [PATCH 1/2] ARM: dts: dra7: Change pbias voltage to 3.3V
Date: Thu, 28 Mar 2019 14:47:44 +0530 [thread overview]
Message-ID: <20190328091745.7893-2-faiz_abbas@ti.com> (raw)
In-Reply-To: <20190328091745.7893-1-faiz_abbas@ti.com>
As per recent TRM[1], PBIAS cell on dra7 devices supports
3.3v and not 3.0v as documented earlier.
Update PBIAS regulator max voltage and the voltage written
in the driver to reflect this.
