mxc_ocotp: Do not disable the OCOTP clock after every access
Leave the OCOTP turned on, so that we subsequent access do not fail.
After enabling the thermal driver on a mx6sxsabresd board:
U-Boot 2015.01-rc1-18267-g99d4189-dirty (Nov 24 2014 - 12:59:01)
CPU: Freescale i.MX6SX rev1.0 at 792 MHz
CPU: Temperature 48 C
Reset cause: POR
Board: MX6SX SABRE SDB
I2C: ready
DRAM: 1 GiB
PMIC: PFUZE100 ID=0x10
MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
00:01.0 - 16c3:abcd - Bridge device
01:00.0 - 8086:08b1 - Network controller
In: serial
Out: serial
Err: serial
Net:
(hang)
As the thermal driver accesses the ocotp registers, its clock will be disabled
afterwards.
Then when the MAC address is read (also from ocotp registers) it will cause a
hang.
Do not disable the ocotp clock to prevent this problem.
