* If sample resistor changes, we need caculate a new CHRG_CUR_SEL[] table.
|
*
|
* Calculation method:
|
* 1. find 20mR(default) current charge table, that is:
|
* 20mR: [1000, 1200, 1400, 1600, 1800, 2000, 2250, 2400]
|
*
|
* 2. caculate Rfac(not care much, just using it) by sample resistor(ie. Rsam);
|
* Rsam = 20mR: Rfac = 10;
|
* Rsam > 20mR: Rfac = Rsam * 10 / 20;
|
* Rsam < 20mR: Rfac = 20 * 10 / Rsam;
|
*
|
* 3. from step2, we get Rfac, then we can get new charge current table by 20mR
|
* charge table:
|
* Iorg: member from 20mR charge table; Inew: new member for charge table.
|
*
|
* Rsam > 20mR: Inew = Iorg * 10 / Rfac;
|
* Rsam < 20mR: Inew = Iorg * Rfac / 10;
|
*
|
* Notice: Inew should round up if it is not a integer!!!
|
*
|
* Example:
|
* 10mR: [2000, 2400, 2800, 3200, 3600, 4000, 4500, 4800]
|
* 20mR: [1000, 1200, 1400, 1600, 1800, 2000, 2250, 2400]
|
* 40mR: [500, 600, 700, 800, 900, 1000, 1125, 1200]
|
* 50mR: [400, 480, 560, 640, 720, 800, 900, 960]
|
* 60mR: [334, 400, 467, 534, 600, 667, 750, 800]
|
*
|
* You should add property 'sample_res = <Rsam>' at battery node.
