Mainline:Broadcom Kona/Power Manager: Difference between revisions
Created page with "* Base address: <code>0x35010000</code> <span id="revisions"></span> == Revisions == There exist two revisions of the Power Manager: REV0 (capri) and REV2 (hawaii, java). Here is a list of known differences: * A second set of voltage controllers is introduced in REV02. ** To go with the second VO, a second sequencer command bank is introduced. * A new i2c command, <code>PWRMGR_I2C_APB_READ_OFFSET</code>, is introduced in REV02. This register contains i2c data and i2c..." |
