+ * This function assumes the expected core clock has to be changed by

+ * core clock (presc=1) unless the core clock is less than PLL_FREQ_MIN.
+ * In the latter case, it will try to increase the presc value until
+ * (presc*core_clk) is greater than PLL_FREQ_MIN. It then makes call to
+ * calc_pll_params() and obtains the values of PD, MFI,MFN, MFD based
+ * on the targeted PLL and reference input clock to the PLL. Lastly,
+ * it sets the register based on these values along with the dividers.
+ * Note 1) There is no value checking for the passed-in divider values
+ * so the caller has to make sure those values are sensible.
+ * 2) Also adjust the NFC divider such that the NFC clock doesn't
+ * exceed NFC_CLK_MAX.
+ * 3) IPU HSP clock is independent of AHB clock. Even it can go up to
+ * 177MHz for higher voltage, this function fixes the max to 133MHz.
+ * 4) This function should not have allowed diag_printf() calls since

As I can see now, this driver is quite a copy of fsl_pmic.c, with
slightly changes. Are you sure we cannot simply change the already
provided driver, adding support for the new chip ?
I have not read the DA9053 datasheet, but from your patch it seems to me
that the relevant changes are:
- registers are 1 byte wide instead of 32 bit
- different size of register area
Really not enough to justify a new driver. All functions are really
copied from the old one. Please consider to adapt fsl_pmic.c instead of
adding a slightly different new one.
Best regards,
Stefano Babic

fsl_pmic is about freescale mc13892 and fsl_pmic.c is dedicated for fsl pmic
as you write this file, right?
As I add the Dialog PMIC support, I do want to not add one new file, but I find
it's not easy to add it and it will make the file very mess, so, I
decide not to touch
the original file and add one new file. The head of this file tell it
clear that this patch is
Based on drivers/misc/fsl_pmic.c.
If you still want me to include the DA9053 support into fsl_pmic,
could you please
extend the fsl_pmic support to easily add another vender's pmic support first?

It was for MC13892, but it is for MC13783 as well, used in i.MX31 boards.

I do not mind an issue related to set where the driver is coming from.
My concern is due to the fact that your patch is very similar (for the
i2c part) to the fsl_pmic.c file, and I want to avoid to have two
different driver making the same things, having then the necessity to
maintain both. At the end, this file expones only a common interface to

Really I have not understood your question. What do you mean ?

Then, Can you tell me how to add the dialog pmic support into
fsl_pmi.c file which is dedicated for
freescale mc13xxx? Thanks,

IMHO the details for each Power Controllers are inside the corresponding
header, that contains the register description, in your xace DA09053.h.
The fsl_pmic.c expones only a general way to speak with the controller
via SPI or I2C interface. If I see your patch, the only real difference
with the original file is that a single byte is read/written with the
DA09053, while the mc13xxx have 32-bit registers. You can add this
option as CONFIG_ switch, or in another way.
Only the board is aware about which PMIC is used. In fact, the
fsl_pmic.c does not include neither mc13892.h nor mc13783.h.
Best regards,
Stefano Babic

Then why not rename the driver to something else than "fsl_pmic"? Maybe
this is what Jason really is asking? I have not looked any deeper, but
maybe something like "i2c_pmic" or such...
Cheers

Yes, of course, no problem at all. Jason, if you meant to drop the fsl_
to make the driver more general, I completely agree. Sorry, I have not
got the point.

Sorry for the late response due to some reason. :(
Yes, We had better rename fsl_ to something else, I would like use generic_pmic
or something else, what's your idea?

I am open for new names. Probably we should state that this driver is a
wrapper when SPI or I2C is used, and something like spi_i2c_pmic gives a
better idea. With generic_pmic we could think there is a general layout
for PMICs (and it is not true).

OK, agree. I will change it to spi_i2c_pmic.c. :)

Stefano is right. We cannot accept such duplication of code. Please
merge into a single common driver.

This patch add initial support for freescale MX53LOCO board.
Network(FEC),SD/MMC,UART have been supported by this patch
The patch also config CPU:1GHZ,DDR:400MHZ for better peformance
Signed-off-by: Jason Liu <jason.hui@linaro.org>
---
Changes since v5:
- merge the "Add power init support" patch
changes since v4:
- remove the boot reset cause from board support
changes since v3:
- include other two small patch into this commit,
mx53loco: set mmc env to MMC slot1
MX5: Enable flat-device-tree support on mx53 loco board
changes since V2:
-factor out the boot cause function to common code,
-fix gd->ram_size with full memory size
-remove the '1' from all #defines that just enable features
-correct memory test end address value
