# STM32F1 PLL configuration options
drivers/clock_control: stm32: Split Kconfig file In order ease readability of Kconfig.stm32 file, split series specific PLL configuration options into series specifc Kconfig files. This being done, we have now a similar pattern for series specific code and series specific Kconfig files. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

kconfig: Global whitespace/consistency cleanup Clean up space errors and use a consistent style throughout the Kconfig files. This makes reading the Kconfig files more distraction-free, helps with grepping, and encourages the same style getting copied around everywhere (meaning another pass hopefully won't be needed). Go for the most common style: - Indent properties with a single tab, including for choices. Properties on choices work exactly the same syntactically as properties on symbols, so not sure how the no-indentation thing happened. - Indent help texts with a tab followed by two spaces - Put a space between 'config' and the symbol name, not a tab. This also helps when grepping for definitions. - Do '# A comment' instead of '#A comment' I tweaked Kconfiglib a bit to find most of the stuff. Some help texts were reflowed to 79 columns with 'gq' in Vim as well, though not all, because I was afraid I'd accidentally mess up formatting.

PLL multiplier, PLL output must not exceed 72MHz. Allowed values:
Density devices: 2-16
Connectivity devices: 4 - 9 and 13 ( used for multiplication factor 6.5).
