There was a mix of UTF-8 and ISO-8859 files in the U-Boot source tree, which could cause issues with the patchwork review system. This commit converts all ISO-8859 files to UTF-8. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>

* AMI FS6377 Clock Generator configuration table
|
|
*
|
|
* the "fs6377_regs[]" table entries correspond to FS6377 registers
|
|
* 0 - 15 (total of 16 bytes).
|
|
*
|
|
* the data is written to the FS6377 via the i2c bus using address in
|
|
* "fs6377_addr" (address is 7 bits - R/W bit not included).
|
|
*
|
|
* The fs6377 has four clock outputs: A, B, C and D.
|
|
*
|
|
* Outputs C and D can each provide two different clock outputs C1/D1 or
|
|
* C2/D2 depending on the state of the SEL_CD input which is connected to
|
|
* the MPC8260 I/O port pin PA11. PA11 output (SEL_CD input) low (or 0)
|
|
* selects C1/D1 and PA11 output (SEL_CD input) high (or 1) selects C2/D2.
|
|
*
|
|
* PA11 defaults to output low (or 0) in the i/o port config table above.
|
|
*
|
|
* Output A provides a 100MHz for the High Speed Serial chips. Output B
|
|
* provides a 3.6864MHz clock for more accurate asynchronous serial bit
|
|
* rates. Output C is routed to the mezzanine connector but is currently
|
|
* unused - both C1 and C2 are set to 16MHz. Output D is used by both the
|
|
* alt-input and display mezzanine boards for their video chips. The
|
|
* alt-input board requires a clock of 24.576MHz and this is available on
|
|
* D1 (PA11=SEL_CD=0). The display board requires a clock of 27MHz and this
|
|
* is available on D2 (PA11=SEL_CD=1).
|
|
*
|
|
* So the default is a clock suitable for the alt-input board. PA11 is toggled
|
|
* later in misc_init_r(), if a display board is detected.
